Abstract (en)
[origin: WO2021253165A1] Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of channel coordination in the unlicensed spectrum. The method comprises receiving, at a first device and from a plurality of second devices, information about carrier sensing to be performed by the plurality of the second devices; determining a transmission pattern for a target second device of the plurality of the devices based on the information about the carrier sensing and information about time sensitive traffic of the plurality of the second devices, the transmission pattern including at least a sensing period for transmission of time sensitive traffic of the target second device and a muting period of the target second device; and transmitting a first message indicative of the transmission pattern to the target second device. In this way, the interoperability of the TSN network device and the normal network device can be efficiently improved in an industrial automation scenario. By controlling the access/transmission of the TSC traffic in the TSC dedicated transmission period, the TSC traffic of the target network device can be protected and the latency requirements can be satisfied.
